Revisiting the 1981 Nobel Prize to Roger Sperry, David Hubel, and Torsten Wiesel on the occasion of the centennial of the Prize to Golgi and Cajal.

In 1981 the Nobel Prize for Medicine or Physiology was awarded to Roger Sperry for his work on the functional specialization of the cerebral hemispheres, and to David Hubel and Torsten Wiesel for their work on information processing in the visual system. The present paper points to some important links between the work of Sperry and that of Hubel and Wiesel and to their influences on neuroscience in the best tradition going back to Cajal.
